There are about 25560 clinical studies being (or have been) conducted in Germany. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
There is increasing evidence that exposure to environmental factors in early development is associated with an increased risk of metabolic and other common diseases. These increased disease risks are likely due to environmental-induced epigenetic changes leading to dysregulation of genes and signaling cascades. The best studied epigenetic modification in this context is DNA methylation. Preliminary studies have already shown that an increased father age or intracytoplasmic sperm injection affects methylation pattern in sperm or umbilical cord blood of children. Unlike sperm, less is known about the methylation of human oocytes and their susceptibility to environmental factors. The aim of this study is to analyze the methylation pattern of immature oocytes of women with decreased fertility. Based on the results of a large number of oocytes from different women, risk assessments could be made for individual factors such as the age of the patient, as well as correlations between the occurrence of changes in gene expression and the unfulfilled desire to have children. In addition, the methylation patterns in sperm from 20 patients are to be examined as reference patterns.
This is an international (North America, Europe, Africa, Asia and Australia), multi-center, prospective, open-label treatment study, designed to continue to provide the study medication to all patients who completed 12 months of treatment (including those treated with placebo) in the IEDAT-02-2015 trial, completed the study assessments, do not present safety contraindication to continuation of treatment, and provided informed consent. The study aims to collect information on the long-term safety and efficacy of the trial treatment.
This study evaluates if a novel form of oral nutritional Supplement application in the form of gumdrops may serve as an alternative to common sip Feeds in cancer patients with high risk for malnutrition. Within this context the Impact of these two different supplements on General condition, Quality of life, muscle function, Body composition, Appetite and Nutrition Status are investigated. Patients are randomly allocated either to a study group with oral Supplementation in the form of sip feed or to a study Group receiving gumdrops for 4 weeks. After a washout period of 5-7 days study Groups are switched for another 4 week Intervention period.
There is a growing body of evidence that surgery and associated morbidities can be omitted without compromising oncological safety in selected patients who have achieved a clinical complete response after radiochemotherapy. However with standard neoadjuvant treatment regimens the pathological complete response rate lies in the range between 10%-20%, the number of patients qualifying for non-operative management is even lower since the sensitivity of currently available diagnostic measures for predicting the pathological complete response hardly surpasses 50%-60%.The hereby proposed phase II trial CAO/ARO/AIO-16 aims at finding novel and innovative aspects of rectal cancer treatment. According to recently published data the radiochemotherapy regime in the present study with consolidating chemotherapy and delayed assessment of response has the potential to achieve pathological complete rates of approximately 40%. A standardized re-evaluation after consolidating chemotherapy will select patients who are candidates for organ-preservation. These patients will not undergo radical surgery and will instead be follow-up closely for tumor regrowth.
Prospective, randomized multi-center trial. Comparison of Endoscopic Mucosal Resection (EMR) versus Endoscopic Full-Thickness Resection with the duodenal Full-Thickness Resection Device (dFTRD) of non-ampullary duodenal adenomas.
This study evaluates the effects of a whole-body electromyostimulation (WB-EMS) training combined with individualized nutritional support on skeletal muscle mass, body composition, muscle strength/function, quality of life, fatigue, pain and gastrointestinal symptoms in patients with hematological malignancies 4-6 weeks before and 4-6 weeks after undergoing stem cell Transplantation. Within this context, this study also investigates the effect of the nutrition and exercise intervention on the period of hospitalization, period of White blood cell recovery and frequency and severity of complications (mucositis, Graft-versus-Host-Disease, infections) after stem cell Transplantation as consequences of the therapeutic immune Suppression.
Given the lack of knowledge on lipodystrophies, the medical and social responsibility for the persons affected by it calls for the monitoring of the progression over long periods of time. Sensible clinical and basic research into rare diseases such as lipodystrophy is only possible in multi-location networks with sufficient case numbers. Also, reliable information on the incidence of certain manifestation patterns, health status, etc. is of utmost importance for health care and health policy in this rare disease. Therefore, the European Consortium of Lipodystrophies (ECLip), an association of European experts on lipodystrophy, has launched a registry (OSSE) for lipodystrophies which is committed to help to improve the research conditions by consolidating this kind of information in a registry.
The primary purpose of this study is to investigate the evolution of Right Ventricular (RV) function before and after left ventricular assist device (LVAD) implantation, using novel echocardiographic quantification of RV size and function in combination with comprehensive hemodynamic, laboratory and clinical parameters. The findings of the study will enhance prediction of early and late development of postoperative right-sided heart failure (RHF) and subsequent mortality and morbidity. The secondary purpose of the study is to combine echocardiographic, hemodynamic, laboratory, and clinical data to define optimal management strategies of RHF after LVAD implantation.
The aim of the study is to investigate the effect of exercise in form of whole-body electromyostimulation (WB-EMS) on early tumor-induced muscular dysfunction. It is anticipated to gain detailed knowledge about composition and metabolism of skeletal muscle cells, and single muscle fiber functionality. To determine key factors leading to impaired force generation and thus decreased muscle strength in cancer patients who are suspected to develop or already show early signs of tumor cachexia is crucial for the establishment of effective cancer treatment. Comparative analysis of skeletal muscle biopsies taken from the abdomen of patients during indicated surgeries will be conducted. The patients will be allocated to the following study groups: a) Study group 1: Patients without cancer, b) Study group 2: Patients with solid tumors who did not perform physical training and c) Study group 3: Patients with solid tumors who executed physical training in form of WB-EMS. The investigation can help to understand skeletal muscle physiology under exercise and to get a better insight into the effects of physical training on early-stage muscle atrophy, both on cellular and molecular level. Initially, it is planned to identify the inflammation and nutrition status of the patients, and to determine skeletal muscle strength. It is anticipated to explore muscle protein composition, particularly myosin to actin ratio and their interaction. Biochemical analysis and the examination of the cellular ultra-structure should enhance the knowledge about the key mechanisms controlling the contractile apparatus of single muscle fibers in order to determine the quality of muscle force. Taken together, these investigations will help to better understand muscle atrophy in advanced cancer patients, and might support the development of targeted anti-cachectic therapies, that can be applied already in early phases of the tumor disease to significantly improve the patients' prognosis and their quality of life.
